Liam Hemsworth was born on January 13, 1990, in Melbourne, Australia, and is the younger brother of actors Chris Hemsworth and Luke Hemsworth. He is the son of Leonie (van Os), a teacher of English, and Craig Hemsworth, a social-services counselor. He is of Dutch (from his immigrant maternal grandfather), Irish, English, Scottish, and German ancestry. His uncle, by marriage, was Rod Ansell, the bushman who inspired the film Crocodile Dundee (1986).

The Hemsworth family lived primarily on Phillip Island, a small island located south of Melbourne. Following in the footsteps of his older brothers, who went into acting in their teens, Liam scored his first audition at age 16 and appeared on the Australian TV series Home and Away (1988) and McLeod's Daughters (2001) before taking on a recurring character role on the soap opera Neighbours (1985), in which his brother Luke had also appeared. Roles on TV shows The Elephant Princess (2008) and Satisfaction (2007) followed before Liam moved to the United States to pursue a big-screen career.

One of the biggest inspirations before I started shooting came from my brother, when he texted me and said, "Hey, fatty, it's called 'The Hunger Games', not 'The Eating Games'.". So I started working out a lot more and eating a lot less.
The Hunger Games (2012) absolutely changed my life. It's brought up so many different questions about my own personal growth and where I was heading. I think, before all of it, I really felt like I had it figured out. Like, you know, it's going to be fine, I'm this person and I know what I want to be and I know where I want to go. But then it got to the point where I think I started double-questioning everything. It was like, why am I doing this? where is it getting me? what if I do this and then I can do this? I wasn't living in the moment.
